A blender internal fully animatable rubix cube. Knock yourself out.

It´s looking cool. But blue and green are oppositing colors on a real rubic´s cube. So You won´t see any real cube like this.
The original cube has white on top and yellow at the bottom. Then the colours on the rim are in counterclockwise order: red, blue, orange, green.
Nevertheless, this is a cool representation of the rubic.
It's cool, the only problem is that each of the cubes on the Blender Model Rubik's Cube are circular and the Blend file is unpacked.
Great
